Sealing Strike (5e Spell)

From D&D Wiki

When you cast this spell, you may make one weapon attack a creature with a ranged weapon. On a successful hit, the ammunition transforms into a spear of light (or darkness) embedded into the creature, preventing it from acting for 1 minute. If the creature takes damage, is moved, or another creature removes the spear, the effect ends. This ability fails if used on a creature of the same moral alignment. Creatures of large size can only be sealed for 1 round, and creatures Huge and larger cannot be sealed.
